To all whom "it may concern:

Be it known that L-Molon JAMEE Don's LAS CARTER; a. subject of the Kine of Eng-- land, residing at Manor ,Psrk, Lon ion, England, have invented certsin new end usefiii 'Im rovements in. Rotary Duplicators, of

which the following is s specification.

This invention relates to improvements in v rotary duplicstors, the object being to pro-- automation vide an eppisretus in whichthe ink can he This invention is particularly applicable to duplicetors of the type descriheo in my United States Patent No. 856444;, that is to say, to those in which the stencil. is carried upon it removable se ment of permeable or orous materiel Whic'i etiords eccess to the.

ink-pad behind the segment for inking per-- poses.

' According to this invention the rotatable cylinder or support carries an ink-pnd as he fore, an external inking roller is arranged. to be op lied thereto during rotation, and the stenci -cnrrying segment can be entirely detsched from the cylinder to enable the pad to be inked by rotating the cylinder or sup-- port.

Any convenient form of inking roller which can be applied to the outside of the stencil-carrier or ink pad mey be ntiiized in a. device embodying this invention.

There are various methods by which the stencil-carrying segment msy be either detsched from the cylinder 01' support, or se cured thereon for use.

In the accompanying drswings:l*igure 1 is a side elevation of one form of rotary duplioator embodying this invention; 2 is s pers cctive View 0 that portion of the rotary du icator which contains the inking device, SLIM Fig. 3 is a transverse section on line 3- -3 of Fig. 2. v

The support or o linder A is errenged to turn on trunnions in the usual way; and by any usual mechanism, and may be provided or' combined with any suitable foam of feeding, gripping end regulating devices. An ink pad A is secured on the surfeceoi this support. metal or the likejs arranged to fitover the pad A and Ill 8Q] itself carry e pad on its )Lll'r. side surface (such; forexemple, es the usual double sheet o'i'linen). The detschehle seg ment C is provided with positioning d.-

such as catches 0 slots to engage pins on the. support, for example at one end of the de techehle segment i], its side flanges C they have little recesses edepted to engage pins A on thefsides oi. the support A and atthe other end oi the detachable segment C stops C niey he errnnqed to engage with one o! .i nore catches on the support A. i ivoted on? the framework l) of the duplicator is e frame E having two end hers with slots E adapted to en age with suitable projections f? on the end this frame is so pivoted that when the detechnbie segment is released from the support A, the frame can be tilted to carry the detschshle segment C clear of the supportil. end to retain it in that position, and the tiitin frame E is for this purpose provided with s. iendle E. The support A. end the pad A thereon ere then free to be rotated without the detnchehle segment C or the. stencil thereon.

A very important feature of this invention resides in the islet thnt the segment or stencil carrier (1 is constructed to en post the stencil throu hout its extent, where iy injury to the stencil is etiectnsliy obviated when removing the some from the cylinder to permit inking oi the pad.

An ink trough is arranged in proximity to the outside of the support A and therotntei. hie inhin roller sri'enged therein, and the spindle o the roller is secured to e bell-crnnh lover or the like, whereby the inking roller may be readily applied to the snrfsce'oi the roteteble pad A. This inking device Will he hereinafter described with reference to Figs. 2 snd'3. When using the apparatus it is only necessary to detnch thesegment C cerrying the stencil carrier to brim the inking rolls? into contact with the ped 26 end to totste the s11 port A in the usual way by means of the hen is F in order to obtain on eficient the inkin outside of e stencil carrier before the stencil has been fixed thereon in order thzttthe outer psd with which the stencil lies in contact may receive a. preliminary supply of ink.

- In order thet the supporting cylinder A may be readily i'oller may also be applied to the brought into proper position 0?. replacing the detachable stencil-carrier C by means of the tiltin frame rot-sting mec ienism they be provided with e'stop or catch which hoids the support in such it position that the Of course tilting frame E will exactly engage with the abutments C or the like on the detachable segment G, and also so that when. the detachable segment has to be replaced, it will come properly into position for engaging the positioning and retaining devices on the support. For example, it little pivoted catch G on the bearings of the driving shaft H may be arranged to engage with a slot F on the driving handle F in a well. known way.

- The stencil-carrying segment C-is apt to adhere with some tenacity to the pad A, and in order that the segment may be liberated clear of the support or drum A.

in my previous British. application No. @335/06 1 have described a mechanism for co htrolling an impression. roller on a rotary diiplicetor and a similar device is em )loyed on the present machine, It will be 0 ,vious that it is undesirable that the impression roller K should be in its raised. position while the stencil-carrying segment is removed be cause the impression roller K might then come in contact with the inked pad A and become soiled. To prevent this, the handle L wh1chcontroie the impression roller K is so arranged that when the nnpression roller 1s 1n its raised positlon, the handle F cannot be turned to bring the tilting frame into operation, so that after a printing operation is over and it is desired to ink the pad A, it is neoessary first to shift the handle L and lower the impression rollerK before the handle F can be brought into operation to remove the stencil-oarrying segment C.

In proximity to the cylinder and parah, lei to the .axis B thereof is a rod M rotatable 1n the framework D of line machine and having secured thereto arms which carry are: tatable inking roller 0. The arms also'support rubbers or doctors P and P for regulat ing the supply of ink on the roller and the pressure of the doctors can be ad usted by means of 2,; spring P and set screw 1. [lo

cordingsflto the movement of the arms N therefore, the roller @Wnay moyle'up to or "away from the c linder A, the doctrine l and P remaining I l n 5 l Beneath the roller (1' is a wide inlr' troughQ which can slide into suitable supports or guides the framework D aways in contactwith the trough I spread.

V or" the machine and can befifiscd-threm by'means of screws lik The rollerO is'arren'ged to dip into the of contact with the cylinder. The spring the path of the and the lever catch T may be pushed out of lever S by means of a button '1 is then free to be shifted to bring the inking roller into operative position. The movement of the lever S is limited by a stop T" which prevents the inking roller from touching the metal parts and the stop can be adjusted (by a screw) so that the roller just touches the ink pad on the cylinder A.

On the spindle at one end of the inking roller is fixed a toothed wheel U by means of which the roller may be fixed. For this purpose an abutment or projection V is pivotedon the arm N in hich the roller is journaled. it can be brought into orout of' engagement with tlie'toothe d wheel U so as to lock the The abutment V is so arranged that inking roller or liberate it. When the mechine is not inuse, the roller Gand trou h Q can be inclosed in a cover W hooked or ot rerwilrie secured to the rod M which supports the re er. s 1

The operation of the inking device is as follows;The stencil carrier is removed from the cylinder A orderto expose the under pad; a supply of ink is introduced into the trough Q t c lever S which controls the'inking roller 0 is released from its spring catch T and is brought towerds the cylinder A until the' handle S enge es the stop T which in sures that the roller u'will just touch the U11: der pad. The cylinder, A is then either revolved or turned backwards and forwards.

In the same way, before placing a new stencil on the stencil carrier the outer pad can be inked by leaving the stencil carrier on the cylinder, bringing the roller into a osition where it will come in contact with t e outer pad and then rotating ofoscilleting the cyllnder.

In order to regulate the amount of ink supplied to the pad it is only necessary to the pressure of the rubbers or doctors P and P on the inking roller 0. In many cas s, however, the under aid already has a slidicient sup ly of ink w l'iich onl requires to be 11 that case the in ing roller is locked by bringing-the ivoted abutment V into engagement with t 1e toothed wheel U: the inking roller 0 ls'th'en brought into conadjust tact with the pad and the/cgr'linder A is ro-' teted in contact with the fix'e V teller whereby the ink is eflectively distributhd; yBefore rc placing tlre stencil on the ma chine, the ihliing roller is withdrawn so that the controlling lever S engages the spring catch T.

In or backwards so as to lift the inking roller out of er to clean the inking devicepia a -"'only necessary to tilt the controlllm lever 55;

sevens the trough Q, then to release the trough from sponding positioning devices on the segment its supports R and withdraw it from the machine.

It is to be understood that the details ef arrangement and construction may be varied without departing from this invention r example, the removable stencil carryings'eg' ment C might be pivoted to two slotted links, the slots in each engaging the spindle'of the drum A so that the stencil carrying segment might either engage the drum and rotate therewith or be removed from the drum and allow the drum to rotate independently.
